Analysis of mineral content in Hotspring Water samples in Tubbe and Aramaba Village, Pantar Tengah District, Alor-NTT

Abstract

Clean water standards are tasteless, colorless and odorless. Hot spring water in Tubbe and Aramaba villages is used by the community for drinking, cooking, washing, bathing and other needs. However, the physical parameters of the water has no longer met the standard because it is slightly colored and has distinctive odor of sulfur. Low quality of water affects the health of people who consume the water. The main problem is clearly seen from the yellow teeth of the people in Tubbe and Aramaba villages. Therefore, it is important to analyzed water quality to determine the levels of iron (Fe), phosphate (PO4)3+ and sulfate (SO4)2- in hot spring water in Tubbe Village and Aramaba Village, Pantar Tengah District. Iron content testing has been carried out using an atomic absorption spectrophotometer. UV-Vis spectrophotometer has been used to test the concentration of phosphate and sulfate. The measurement results show that the hot spring water samples in Tubbe Village contain 0.04mg / L iron (Fe), 0.09 mg/L phosphate (PO4)3+ and 11,31mg/L sulfate (SO4)2. This value is below the maximum threshold, according to Minister of Health Regulation No. 149 of 2010. The results of the Aramaba Village are 0.04 mg/L; 0.09 mg/L and 11.31 mg/L for iron (Fe), phosphate (PO4)3+ and sulfate (SO4)2-. This value is above the threshold of calcium content according to Minister of Health Regulation No. 149 of 2010.
